This document is a technical standard detail drawing (Detail No. SD-300) for a Reclaimed Water Valve Box and Cover, issued by Michigan Water on 6/97 and revised on 8/00. The drawing provides precise engineering specifications for a cast iron valve box and cover designed for reclaimed water infrastructure, with specific dimensional requirements for the valve box, cover, and associated components. The technical drawing references Standard Specification 1426 and specifies that all materials shall be cast iron per ASTM A-48, Class 30 B.

Key technical specifications include requirements that the valve box have a round bottom to accommodate riser pipe, with a square top, and surfaces that are smooth and free of casting ridges. The lid and inside/outside of the riser pipe must be colored purple, either during manufacture or painted afterwards, with the specific paint being Seymour Safety Purple. The drawing includes detailed section views and measurements for the valve box cover and box, with precise tolerances for dimensions, taper, and lettering. Lettering is restricted to what is shown on the valve box cover, with 3/4" raised letters at 1/8" height.
